  2. Covalent bond - Wikipedia

    en.wikipedia.org/wiki/Covalent_bond

    A double bond between two given atoms consists of one σ and one π bond, and a triple bond is one σ and two π bonds. [8] Covalent bonds are also affected by the electronegativity of the connected atoms which determines the chemical polarity of the bond. Two atoms with equal electronegativity will make nonpolar covalent bonds such as H–H.

  3. Polyatomic ion - Wikipedia

    en.wikipedia.org/wiki/Polyatomic_ion

    As the number of oxygen atoms bound to chlorine increases, the chlorine's oxidation number becomes more positive. This gives rise to the following common pattern: first, the -ate ion is considered to be the base name; adding a per-prefix adds an oxygen, while changing the -ate suffix to -ite will reduce the oxygens by one, and keeping the suffix -ite and adding the prefix hypo-reduces the ...

    The rest are named with a Greek numeric prefix, with the exceptions of nonane which has a Latin prefix, and undecane which has mixed-language prefixes. Cyclic alkanes are simply prefixed with "cyclo-": for example, C 4 H 8 is cyclobutane (not to be confused with butene ) and C 6 H 12 is cyclohexane (not to be confused with hexene ).

  5. Organic compound - Wikipedia

    en.wikipedia.org/wiki/Organic_compound

    Mellitic acid, which contains no C-H bonds, is considered a possible organic compound in Martian soil. [15] Terrestrially, it, and its anhydride, mellitic anhydride, are associated with the mineral mellite (Al 2 C 6 (COO) 6 ·16H 2 O). A slightly broader definition of the organic compound includes all compounds bearing C-H or C-C bonds.

  6. Bonding in solids - Wikipedia

    en.wikipedia.org/wiki/Bonding_in_solids

    As noted above, covalent and ionic bonds form a continuum between shared and transferred electrons; covalent and weak bonds form a continuum between shared and unshared electrons. In addition, molecules can be polar, or have polar groups, and the resulting regions of positive and negative charge can interact to produce electrostatic bonding ...

  7. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    Molecules that are formed primarily from non-polar covalent bonds are often immiscible in water or other polar solvents, but much more soluble in non-polar solvents such as hexane. A polar covalent bond is a covalent bond with a significant ionic character. This means that the two shared electrons are closer to one of the atoms than the other ...

  9. Methyl group - Wikipedia

    en.wikipedia.org/wiki/Methyl_group

    It is a very stable group in most molecules. While the methyl group is usually part of a larger molecule, bonded to the rest of the molecule by a single covalent bond (−CH 3), it can be found on its own in any of three forms: methanide anion (CH − 3), methylium cation (CH + 3) or methyl radical (CH • 3).
